The present study is predicated on the logic of interrelated functional information processing components as an approach to
understanding reading and its difficulties in preadolescent readers. The structural equation modelling (and its variants)
involved these three latent components: (a) orthographic/phonological component, (b) morphological component, and (c) sentence
and paragraph comprehension component. These components were subserved by a total of ten measurable tasks, all administered
on-line via the microcomputer under laboratory conditions with reaction time measures as indices of mental representation
of word knowledge and sentence/paragraph comprehension. The latent dependent component of reading performance was subserved
by standardized vocabulary and reading comprehension tests. The total sample consisted of 298 children in grades, 4, 5, and
6. Maximum likelihood analyses using LISREL show that the data in general do not disconfirm the proposed model for grade 4
readers. The three-component model, with some variables set free, provides a reasonable fit for the grade 5 data but less
claim could be made about the goodness of fit for grade 6. The results show the mutually reinforcing and mutually facilitating
effects of multilevels and multicomponents of reading. Word structure and word knowledge are particularly predictive of reading.
The present Phase 1 work would be validated in a follow-up of another cohort of readers and would also lead to the systematic
training of some of the components with poor readers.

This introductory essay reviews the key contributions of David Teece's landmark paper “Profiting from Innovation” published in research policy in 1986. It summarises the contributions of each of the papers in the special issue. It then offers some perspectives on the key themes emerging from these papers, and on the broader challenges facing researchers, strategists and policymakers in the field of technology innovation today. 相似文献

This paper presents an evolutionary framework for horizontal technology policies (HTPs) especially market-friendly ones involving project-based incentives (e.g. R&D project based grants rather than tax-based incentives to yearly expenditures on R&D). HTPs are a category of technological policies whose objective is to promote technological development per se, and associated management and organizational routines, irrespective of industrial branch or technological area. They are being increasingly adopted by both advanced countries and newly industrialized countries in response to the new opportunities and threats opened up by the technological revolution and by the processes of liberalization and globalization; and they complement the more specific and well-known selective and vertical policies aimed at individual sectors and technologies. The analysis is conducted within a learning-to-innovate framework with emphasis on collective, organizational learning; search; and market-building. The outcome is a technology policy cycle with distinct infant, growth, and mature phases. Proactive ‘generation’ of a critical mass of projects for efficient learning and diffusion of innovation routines becomes the aim of the infant phase; while the mature phase of the policy should focus on policy restructuring including drastic reductions in the support of routi projects and enhanced support of more complex types of innovation. The paper also emphasizes the importance of a neutrality component in incentives in the infant phase of increasing selectivity; and of building policy capabilities for efficient policy design and implementation. 相似文献

There is ongoing debate about children's ability to use subsequently acquired language to describe preverbal experiences. This issue was addressed experimentally in this investigation using a novel paradigm. Two-year-old children who lacked color words were individually taught to activate a bubble machine by selecting a particular color of bubble solution. The children then participated in weekly, experimenter-provided activities that fostered their acquisition of the color labels. After 2 months, their ability to apply the newly acquired words in reporting the original event was assessed. A significant proportion of the children demonstrated verbal recall when prompted in the presence of physical reminders of the event. These findings indicate that some early, preverbal memories are translated into words at a later time. 相似文献

The present study examined the role of verbal working memory (memory span and tongue-twister), two-character Chinese pseudoword reading (two tasks), rapid automatized naming (RAN) (letters and numbers), and phonological segmentation (deletion of rimes and onsets) in inferential text comprehension in Chinese in 31 less competent comprehenders compared with 37 reading comprehension control students and 23 chronological age controls. It was hypothesized that the target students would perform poorly on these cognitive and linguistic tasks as compared with their controls. Furthermore, verbal working memory and pseudoword reading would explain a considerable amount of individual variation in Chinese text comprehension. RAN would have a nonsignificant role in text comprehension. Structural equation analyses and hierarchical multiple regression analyses generally upheld these hypotheses. Our findings support current literature of the role of verbal working memory in reading comprehension found in English. The results, however, suggest differential role of the constructs and the tasks in reading comprehension and provide some answers for comprehension impairment in Chinese students. 相似文献

This study examined cultural reflections online of audience comments on social network sites regarding vocal talent shows in China and the United States. The study applied dimensions of cross culture to investigate audience comments on the official social networking sites of The Voice of China and The Voice. Findings reflect Hofstede’s dimensions as applied to social media and illustrate how individuals alter their “local” cultural norms in the new media environment. The study specifically enhances the exploration of cultural manifestations in cyberspace, which fewer cross-cultural studies have researched. 相似文献
